+
+#### Step 1. Data preparation
+
+For English, words are used as units. Please prepare a list of commands written in a text file `commands_en.txt` of the following format:
+
+```
+# command_id command_sentence
+1 TELL ME A JOKE
+2 MAKE A COFFEE
+```
+
+For Chinese, pinyin are used as units. [multinet_pinyin.py](./multinet_pinyin.py) help to get Pinyin of Chinese. Please prepare a list of commands written in a text file `commands_cn.txt` of the following format:
+```
+# command_id command_sentence
+1 da kai kong tiao
+2 guan bi kong tiao
+```
+
+#### Step 2. Move created files
+
+1. Move your `commands_en.txt` or `commands_cn.txt` to `/model/multinet_model/fst/`
+
+## MultiNet5
+####  1. Install g2p_en, please refer to https://pypi.org/project/g2p-en/ 
+
+```
+pip install g2p_en
+```
+
+#### 2. Run multinet_g2p.py
+
+```
+python multinet_g2p.py -t "hello world,hi ESP;turn on the light;turn off the light"
+
+------
+in: hello world,hi ESP;turn on the light;turn off the light
+out: hcLb WkLD,hi fST;TkN nN jc LiT;TkN eF jc LiT;
+```
+
+#### 3. Add speech commands 
+
+##### 3.1 add speech commands by menuconfig
+
+```
+idf.py menuconfig
+ESP Speech Recognition -> Add speech commands
+```
+
+
+
+##### 3.2 add speech commands by reset function
+
+```
+// Function definition
+// typedef void (*esp_mn_iface_op_reset_t)(model_iface_data_t *model_data, char *command_str, char *err_phrase_id);
+
+// "," is used to split different phrase with same command id
+// ";" is used to split different command id
+char *new_commands_str="hcLb WkLD,hi fST;TkN nN jc LiT;TkN eF jc LiT;"  //
+char err_id[256];
+multinet->reset(model_data, new_commands_str, err_id);
+// hello world,hi ESP -> commond id=0
+// turn on the light -> commond id=1
+// turn off the light -> commond id=2
+```
